Talking about the New Year at the beginning of June is, of course, a bit original. But, as the saying goes, prepare a sleigh in the summer. In addition, such an LED strip as SMD 2835 is useful not only for decorating a Christmas tree. Its multi-colored overflows can create a festive mood in a number of other holidays. And when folded, such a tape takes up little space, is inexpensive, and will be quite a good purchase for the price at which it is offered by a number of sellers on the website of the Chinese retailer AliExpress. The owners and management of the AliExpress site, which is part of the Alibaba Group, sometimes experience bouts of motivated greed. How else to explain the fact that from June 1, 2017 they cut cashback for Russia and the CIS countries to 5.5%, and in fact to 5% on the website of a number of partner sites, such as this. At the same time, cashback on cell phones and smartphones will be even less, a maximum of 3.5%. Experts explain what happened simply. The owners of AliExpress felt that our market had already been conquered. From Russia and the countries of the so-called CIS, a lot of purchases are made on AliExpress sites. But Western European buyers from France and Spain are welcomed there with open arms. Therefore, for the French and Spaniards, the cashback will be 9% for the main groups of goods. For Americans, a little less, but for them, cashback, as well as for all other countries of the world, remains at the level of 7%. AliExpress has a store called goodland Official Store. It trades mainly in various LED products. The seller is decent, the order sends and delivers quickly, literally in two to three weeks. The complete set of LED strips on the pages of his site can be very diverse, with single-color or multi-colored (RGB) LEDs, with or without a remote control, with or without power supplies. Separately, buying a power supply is not entirely profitable, and required for 12V. and current 2A. PSU will usually cost from 300 rubles and more. More powerful will cost even more. Therefore, it is better to purchase an LED strip already complete with a power supply, it will generally come out cheaper. The connectors of such tapes are arranged in such a way that the segments of the tapes can be articulated with each other, and they will work like a train if such a tandem pulls the power supply. The LED strips themselves, in addition to the fact that they can be ordered in a single color version with white, red, green and blue LEDs, also vary in length. Usually the length of the tape is from one to 5 meters. A one-meter tape, for example, is not entirely profitable to take, it is short, but it costs a little less longer. Therefore, the most profitable option is a 5-meter tape, and if necessary, it is easy to shorten it. The LED strip is designed for a certain number of flexion / extension cycles. But it should be remembered that the entire tape is a long and narrow printed circuit board with copper tracks, and LEDs and quenching resistors soldered to them. Therefore, it is easy to damage it, and such damage can disrupt the normal operation of the entire tape. Based on this, the handling of the tape requires careful and accurate. sharp bends should also be avoided. In addition to the decorative function, such a tape, for example, from white LEDs, can be used for lighting, decorating rooms, furniture, offices, etc., and even for vehicle modding. But this is already an amateur. The SMD 2835 LED strip is designated as such by the type of body of the used LEDs "2835". But the fact that these LEDs do not have classic wire leads is already designated as the SMD type of radio components. Such parts allow only surface mounting, which is used on the tape. Today, the specified seller has a price for such an LED strip at 805 rubles. But it has been crossed out, and for the remaining two days the price for the kit is only 523 rubles. Taking into account the complete set with a power supply and a remote control for a 5-meter LED strip, equipped with a scattering of bright LEDs in three emission colors, this is quite a bit. The whole set is in front of us: The switching power supply of the kit was packed in a separate box. It has an output voltage of 12V. and maximum output current in 2A: The output plug of the block is standard 5.5x2.1, and is great for a number of electronics, for example, for such a device. And also for modern surveillance cameras like this, and a number of other electronic devices designed for 12V. power supply: Thus, taking into account the fact that such a power supply costs more than half the price of the entire kit, and its application can be universal, there is very little left for the cost of the LED strip itself. Without a doubt, a similar kit for the price required by the seller is 523 rubles. will be a good buy. The power supply has a blue LED indicating the connection to the network, and its output voltage is consistent with the declared: The packaging of the rest of the kit is also very civil: It is indicated that the tape must be protected from water. Ribbon at work: The combination and speed of light waves is the most diverse: The desired speed and combination of lighting effects can be selected from the complete remote control, which controls the operation of the LED controller, placed in a separate white plastic box: It should be noted that it is better not to run a tape rolled up on a reel for long-term operation. Otherwise, the LEDs and other electronic components of the tape overheat, and the overall heating of the tape wound on the coil reaches a very high value. An unrolled LED strip cools much better, and the heating of its electronic components in this mode of operation will be quite moderate. In general, the whole set works quite reliably and variously, and the quality of its manufacture, including the power supply, should be recognized as high, almost branded.
